To allie/10m it may confer-1t:

lle it lnoivn that I. Henin-intr F. PROVAN- inn, a citizen of the United States, residing at Melrose, in the county ot Middlesex and State of lllassachusetts, have invented an Improvement iii Machines for Forming Paper Receptacles, of which the following is a specilication.

Certain kinds ot' paper receptacles are composed of frusto-conical bodies and bottom-pieces having` notched edges bent to form a flange, which Harige is adapted to extend over the outside, or it may be the iiiside oi the loiver ends of the bci-ily, and to be secured thereto by paste or other adhesive material which is herein termed paste.

This invention-has .t'or its object the construction of a machine for securing the tianged bottoin-pic -cs to the bodies and censists in the combination ot' a forni of a shape corresponding to the shape of the completed paper receptacle upon which the body placed, and also the bottom-piece, and a pressure-device, made as an inverted cup or otherwise formed coextensive with the bottoin-piece, adapted to be moved into engagement with the bottoni-piece on the form to press itsl flange into riii engagement With the end-portion of the body, and means to support said pressure-device to admit of its being moved toward and from'the form, said supporting-means having associated With it means to hold it iii both its engaging and disengaged positions. Automatic means are or may be provided for moving the pressure-device out of coperative relation with the form to disengage and permit removal of the receptacle from the form, and said automatic means may be so constructed as to admit of manual movement of lthe pressure-device into cooperative relation with the form to engage the bottom-piece. 'The machine'also embodies means for heating the paper receptacle while it is held by the pressure device, thereby to dry and cause the adhesive material to set.

The machine involves a turretand ak plurality of forms thereon, each lform having associated with it a pressure-device and supporting-means therefor, but in such case the heating of the paper-receptacles Will be done at a, certain part of the cycle of operation of the turret, hence heating-means are provided only at a certain place, which is so ar- .parts of a paper receptacle thereon,

ranged that as the turret rotates the forms with the receptacles thereon will be brought successively into position to become heated.

Figure l is a plan vieiv of a machine for lforming paper receptacles embodying this invention. F ig. 2 is a vertical section of the machine shown in Fig. l, taken on the dotted line Q-2. Fig. 3 is an enlarged side elevation of one. ot' the forms with the component n its pressure-device and supporting-means therefor; the holding-means for the supporting-means and automatic means to move said supporting-means. Fig. 4 is a detail View of the automatic moving-means for the supportingineans. Fig. 5 is a rear elevation o'f one of the lforms and parts associatedtherewith. Fig. (i is a side elevation of a completed receptacle, such as may be found on this niachine embodying this invention.

l() represents the turret on which a plurality of forms 'are erected, which is made as a table.4 Said turret is secured to a sleeve l2 rotatably mounted on a stationary spindle 13, which is suitably7 supported. Said sleeve has secured to it a. bevel-gear l5, which is engaged by a bevel-gear 1G, secured to a power-dr. ven shaft 17. The turret is or may be continuously rotated by said power-driven shaft. A The forms which are erected on the turret and upon which the paper receptacles are formed are made of a shape corresponding to the shape of the receptacles to be formed. As the paper receptacles here shown, see F ig. 6, is of frusto-conical shape a truste-conical form is represented at 20. Said forms are here shown as stationarily supported onthe turret byv any suitable means, so far as this inventionis concerned. The body 60 of the receptacle, which has been previously' constructed and also provided ivith a line of paste around the outside of its small end-portion, is placed on the forni. and then the bottom-piece, having a notched or other form of flange and Which has been previously made, is placed on the form ou top of the body, although it Will be `obvious that their positions with respect to each other may be reversed. Then, it is herein designed and intended that pressure shall be applied to the bottom-piece and particul arly to the flange thereof t0 firmly press it into engagement Wit-h the body and hold it while the adhesive material dries or sets.

here own, of suitable size and s which is loosely connected at :rvu 29 0f which S plvoted at gagement center.

The l,degree of pressure which is applied to the determined by thel may be required,

extending across the cording t the position of the an...

After the operator has placed a body and form she moves the supporting-arm by hand to depress the prestacles, the combination lof a whereupon the springs act to assist such movement, and thereafter hold the cup in tirm engagement with the supporting-arm is moved 1n the other direction by automatic means, provided for the purpose. As here shown said automatic means consists of a stationarily supported cam a bottom-piece on the sure-device or cup,

bottom-piece until said the machine-frame,

on the supporting-arm,

on its pivot 30 and lift be observed' that one side of the machine, as at vreceptacle from the form and place ythe form a new body and bottom-piece, and 'then depress the supporting-arm by hand andthe movement of t As a Iressuredevice an inverted cu 25, is ape to it upon the top of the form, and said cup bas-an ear 26, centrally disposed uponit, 27 to one arm 95 of anangularly formed lever, the other Y 30 to a' stand on the turret, therebv supporting the cup above the form and permitting it to be movedl up and down or into and out of enwith a bottom-piece on the form. In order that the cup 25 may bear upon the bottom-piece with substantially an equal pressure over all, the supporting-arm 28 hasat its extremity a projection 35 arranged to engage the cup at one side of the center `and exert downward pressure thereupon when the supportin,f garm is depressed to y move the cup into engagement with the bottom-piece, and a strong leaf spring 3G is secured to the supporting-arm which bears upon the cup at the opposite side of thel 45 arranged on which is adaptedto be engaged by an inclined yielding inger 4:6 as represented in Figs.` 3 and 4, which actsvto move the arm the pressure-device. fAs theturret rotates continuously it will the operator may sit at for inpaper upon stance, and may remove the completed e turret is suliciently acts while the form passes infront of her. It is desirable to heat the paper receptacles to` dry the adhesive material and better cause it to set, and, as here shown, one or more gas-burners 50, may be arranged beneath the turret'at some point usually well removed from the operator, which act to heat the turret and the forms thereon and the paper receptacles on the forms, but so far as this feature of my invention is concerner] other heating-means may be employed.
